SIP Trunking

Compared to ISDN our SIP trunking service is less costly per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and provision and, as standard, it delivers extremely robust business continuity.

The service can support connections ranging from two channels for small PBX-equipped businesses to an unlimited number of channels for large enterprises and contact centres.

How Resilient is SIP?

SIP Trunking is now a mature service enjoyed by thousands of UK organisations and this alone is testimony to the reliability of SIP. For added reassurance while you switch to us, SIP Trunking can even be used with existing ISDN connections to ensure the transition goes smoothly.

What's the Quality Like?

From the moment we connect your SIP trunking service, you will enjoy all the reliability, resilience and quality that comes from being on the UK's fourth largest network. We proactively monitor and manage quality of service across our entire network - it’s the underlying network quality that makes a real difference to SIP Trunking. And as a consequence we are able to support both G.729 or G.711 codecs.

Disaster Recovery

Did you know that a recent survey by AXA Insurance found that after an office disaster such as a fire or flood, 80% of businesses never reopen or close within 18 months? Scary statistics. But should disaster happen, you can use SIP trunking to minimise disruption to your business. For example, if your London branch has to close in an emergency, and you need the calls routed to Manchester immediately, Reefstream SIP Trunks can do this and at no extra charge to you.

Flexibility

Number flexibility with SIP trunking means that you can keep your existing number, even when moving out of the area, saving you costs on printed company literature and stationery whilst maintaining the perception that you still have a presence in the area you’ve moved from.

We can easily transfer your old or existing numbers too so that you can avoid expensive Remote Call Forwarding (RCF) or call diversion charges.
